An amazing link: Interactive photograph of the entire night sky

The Photopic Sky Survey is a Web site with a 360-degree, interactive composite photograph of the entire night sky as seen from Earth.

In it we see tens of millions of stars, the glowing factories of newborn ones, and a rich tapestry of dust all floating on a stage of unimaginable proportions.

Assembled and photgraphed by Nick Risinger, it's a 5,000 megapixel photograph of the entire night sky stitched together from 37,440 exposures. Large in size and scope, it portrays a world far beyond the one beneath our feet and reveals our familiar Milky Way with unfamiliar clarity. When we look upon this image, we are in fact peering back in time, as much of the light—having traveled such vast distances—predates civilization itself.

"Seen at a depth thousands of times more faint than the dimmest visible star, tens of millions of other suns appear, still perhaps only a hundredth of one percent thought to exist in our galaxy alone. Our Milky Way galaxy is the dominant feature, its dusty arms sweeping through the frame, punctuated by red clouds of glowing hydrogen. To the lower right are our nearest neighbors, each small galaxies themselves with their own hundreds of millions of stars."
